The preparation of novel 5-amino or 7-hydroxy substituted pyrazolo[4,3-b]pyridine and pyrazolo[3,4-c]pyridine acyclic C-nucleosides is described. Their synthesis was carried out by condensation of suitably substituted lithiated picolines with 2-benzyloxyethoxymethylchloride followed by pyrazole ring annulation. The compounds were evaluated for their antiviral activity against a wide panel of viruses
描述了新颖的5-氨基或7-羟基取代的吡唑并[4,3-b]吡啶和吡唑并[3,4-c]吡啶无环C-核苷的制备。它们的合成是通过适当取代的锂甲基吡啶与2-苄氧基乙氧基甲基氯化物的缩合,然后进行吡唑环环化来进行的。评估了这些化合物对多种病毒的抗病毒活性,但发现它们在亚毒性浓度下无活性。
